PLT, platelet; MPV, mean platelet volume; PDW, platelet distribution width; APTT, activated partial thromboplastin time; TT, thrombin time; PT, prothrombin time; AHI, apnoea-hypopnea index; ODI, oxygen desaturation index; MAI, microarousal index; CT90, percentage of sleep time with oxygen saturation below 90%. The bold values indicate a statistical significance (p<0.05).
